Inheriting characteristics of pore Evolution in Daanzai limestone Reservoir of lower Jurassic, Central Sichuan

摘要

The formation, preservation and destruction of pores are dependent on the type and degree of diagenesis reservoir rocks underwent. For a special type of diagenesis, its function on reservoir characteristics is definite. However, pore evolution is not a state but a forward process. Pores are not only the result of earlier diagenesis, but also the basis of later diagenesis. Earlier diagenesis has great influences on later diagenesis and pore evolution.
